To all whom t may concern:

Be it known that I, GEORGE VAN BOLT, a citizen of the United States of'America, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Ruling-Machines, of which the following is a specification.

The present invention relates to improvements in ruling machines, and is designed Y especially for use in ruling wax forms to produce matrices to be utilized in the process of electrotyping.

The case of wax is properly supported, and its surface is ruled by the co-action of the supporting table for the case anda small cutting tool resembling a knife blade or chisel. Y

The customary manner of producing the lines in the matrix is to have the complete form including the set type, cuts, and all rule set up by the printer from which the matrix or wax mold is produced, and then, by an electrolysis process the electrotype is produced. This. process of preparing the electrotype is expensive composition work by the printer, especially on complicated forms of line ruling having lines extending both horizontally and vertically or at right angles to each other in the same form.

By my method and machine, it is necessary only for the printer to set up the type matter and cuts, then from this form a mold is made in wax, after which the lines or rulings are made in the wax as desired.

In the art to which this invention applies, a thin metal slab coated with a wax covering is called a case, and after the impression is made On the case it is calledl a mold and in the following specification for convenience of 'description I shall refer to these parts by these terms. y

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention con` structed according to the best mode havey so far devised vfor the practical applicationv of the principles of mylinvention.

Fig. 13 is a detached view of the knob on the' cutter or tool head,and Fig. 14 is a plan` view of a rack disk on the stem of the' cutter or tool head. l

In the preferred embodiment of my invention as illustrated Yin the drawings the machine is adapted to alternately rule lines at right angles to each other/L'. e. by a movement of a reciprocable table longitudinal lines or rules are marked on the wax, and by a transversely movable carriage which is reciprocable the laterally extending lines are marked.

The machine is-supported upon the rectangular frame l equipped with the four corner legs 2, and as seen in the top plan View (Fig. 3) the top of the frame is open, and at its sides has a pair of rails 3,3, extending longitudinally of the frame and forming a track way-or guide for the lon- Y gitudinally Vreciprocable table i which is formed withA sides or flanges 5,5', V-shape in cross section. These flanges are adapted to slide in the grooved Vways or track rails 3, 3' as the table is reciprocated, and adjacent each' end of the frame of the machine a stop` block 6 is'ixed onl the rail to limit the movement of the table. These blocks vare slidable on Vthe rails and may be adis journaled in the sides of the framey asy shown Vin Fig. 5 5 and projects at one side thereof to accommodate the hand wheel 11 xed'upon' its vend. By means of the hand wheel, it will readily be seen, the table may be moved forward and reversed longitudinally of the frame, through the con? nection with the rack bar of the pinion or rack wheel on the transverse shaft. In this manner the longitudinal movement of the table is produced in order to mark the longitudinally extending rules or lines in the wax.

The wax sheet upon which the lines are to be ruled is not shown in the drawings, but when in proper position is laid upon the adjustable table top 12 and by means of the adjusting screws 13 threaded into and through the table proper, the wax sheet or mold may be trued and leveled, and when adjusted to proper position, the set screws 15 in the transverse straps 14 may be used to clamp the mold in place. These straps are supported above the tablefrom the blocks 16, 16 which are of dovetail shape in cross section and slidable in the dovetail grooves 17, 17 in theA sides of the table 4, and the blocks may be moved from end to end of the table in these slots, the set screws 18 being used to hold the blocks in fixed position. There are two of the straps 14 shown in the drawings and each strap is provided with four clamping screws, to clamp the mold or case, but it will of course be understood that the number of straps and the number of clamp screws may be varied to suit different conditions.

As before mentioned, the table may be reciprocated through the action of the rack bar and its pinion from the hand wheel, for long and rapid movements. l employ an adjusting mechanism by means of which the table may be moved forward or back, which is designed for short moves and close adjustment of the table to position and comprises a screw bar 19, extending longitudinallv of the frame, and journaled for rotation in the cross bracket or arm 20. The bracket 20 as best seen in Fig. 4 has a pair of V-shaped ribs 21 slidable in the V-shaped grooves or ways 3 of the frame 1, and in Fig. 3 it will be seen that the bracket spans the distance between the two rails and is movable with the table when the latter is moved. Tr it is desired to move the table to adjust it accurately for spacing lines, the screw bar 19 is turned by means of the hand wheel 22, but first the bracket 20 is clamped to the rails 3. This clamping is accomplished by means of the handle 23 and screw 24 the latter threaded through the overhanging side 25 of the bracket. Thus, with the bracket clamped and rigidly held on the rails 3, when the wheel 22 is turned the screw bar is turned in the nut 26 fixed to the table, and the table is moved toward or away from the bracket 20. The nut 26 is preferably a split nut and it may be tightened on the screw bar to take up wear. When the wheel 11 is used to move the table, the clamped bracket 20 is released from the rails so that it may move with the table and the wheel 22 and screw 19 move with the bracket.

The lateral or transverse ruling device is located above the longitudinal ruling device and suspended above the table by means of the side arms 27 27 attached to the frame and projecting upwardly therefrom. These f side arms are connected by means of the transversely arranged channel beam or bar 28, and the side flanges 29 29 of this channel bar have V shaped grooves 30 30 in their upper edges in which the ribs 31 31 of a transverse carriage 32 slide. This carriage is a long bar adapted to reciprocate transversely of the table and its supporting frame and in its movement the carriage is guided in the grooved ways of the channel bar. The carriage is moved through the medium of the screw bar 33 which is supported by end brackets .34, 34 attached to the channel bar 28 and the screw bar may be revolved in these bearing brackets by means of the hand wheel 35 at one end of the bar; The screw bar yis adapted to co-act with the threaded nut 36 through which it passes, and this nut, which has a pair of clamping jaws 37, 37, may be moved to adjusted position with rela- .tion to the carriage and i'iXed thereto by means of the clamp screw 38 and its handle 39. When the handle is turned the jaws are clamped on the dovetail rib 40 which is integral with and extends the length of the top of the carriage. This nut is also split and provided witha clamping or set screw 41 which may be turned to take up wear. Thus, with the nut 36 fixed to the carriage, it will be evident Vthat when the hand wheel 35 is turned tov revolve the screw bar, the stationary bar will cause the nut to travel and carry with it the carriage, and the latter is made to slide in its guide ways. To limit the movement of the carriage I employ a pair of sleeves V42 42 each of which is movable on the rod 43 supported in the brackets 34 at the ends of the beam 28, and by means of the set screws 44 the sleeves may be secured in adjusted position to stop the movement of the traveling carriage.

, The ruling or cutting blade 45 is held to its stem 46 by the nut 47, and this stem is carried by the head 48 which ,is attached by means of its perforated lugs 49 to the carriage 32 and moves bodily Vwith the carriage whenv said carriage is moved by power applied to the handle 50 lined thereto. The cutting blade is movable and adjustable vertically by means of the rack sleeve 51, which incases the stem 46, and the pinion 52 on shaft 53. The shaft may be revolved by the thumb nut 54 on-shaft 53 to raise or lower the cutting or ruling tool or blade, and the tool may be held in Xed position by turning a thumbnut 55 on the threaded pin 56 to clamp the split portion 57 of the head about the sleeve (see Fig. 12). The sleeve is prevented from revolving by a key 58, but the stem is designed to be turned or revolved in order that the cutting or ruling blade may be turned to rule lines at different angles. Thus the stem is provided with a knob 59 xed by the pin 60 at the upper end of the stem and this knob has a lug or finger 61 projecting radially therefrom. At the upper end of the sleeve 51 a head 62 is provided and the knob and head co-act to hold the stem in adjusted position. As best seen in Fig. 14 the sleeve head is a circular disk having four notches 63 any one of which is adapted to receive the iinger 61 of the knob 59. The cutter or ruling tool may be turned as desired by first pulling up on the knob 59 against the tension of the spring 64, coiled about the stem between the rack sleeve 51 and the nut 47. The Enger of the knob is lifted from its notch, then the stem is turned in the rack sleeve to the desired position, and the spring is permitted to return the stem to extended position, with the finger in the proper diametr'ically arranged notch 63.

In operating the ruling machine, the wax sheet on its thin metal slab, forming the case is first laid upon the adjustable top 12 of the table, and then, by means of the four corner screws 13 in the table, the case is trued into accurately disposed position. The clamping straps 14 and screws 15, are now brought into use and the case is rigidly and firmly secured in place, whereupon the machine is ready for work.

The cutting tool is brought to desired position with relation to the wax sheet by means of the rack sleeve and its pinion, so that its point will mark the wax surface or rule the lines. Thus with the cutting blade at its initial point at either side of the table, when the hand wheel 11 is turned the table with its wax sheet is moved under the blade and the blade rules a line, to draw the longitudinal line, whereas, to rule the transverse lines, the table is held stationary and the cutting tool is reciprocated by moving the carriage with manual power applied to the handle 50.

In both cases of the screw drive 19 and 33, the threads are cut nine to the inch, each thread of course being 1/9 of an inch or equal to 8 points (type measure). In Fig. 3 it will be noted that the hubs 22 and 35 are graduated or marked into eight parts adapted to register with the index line A on the bearing of the bracket 20 and the other as B on the bearing of a bracket 34. Therefore the space of one graduation on the hand wheels is equal to 1/72 or one point (type .a simple matter to move the cutting tool to position to rule the lines with accuracy and j regularity.

The small blocks 6 on thetracks 3 prevent the parts from running oif the frame, and in many instances are used Vto limit travel of the carriage instead'of the hand wheel and screw, when running long cutsv vturned down at the ends of the table out of the way while the case is being leveled to pociprocable along said rails and a tool forv ruling the work in one direction, a bracket slidable on the rails and connected to the table to move therewith and means forl clamping the bracket to the rails for holding the table stationary when desired, av
